A VNIR spectral database of terrestrial magmatic rocks for the interpretation of Martian plagioclase hyperspectral detections

Barthez M., Flahaut J., Guitreau, M., Pik, R., Ito, G., Delangle, C., Gremilliet JP, Luais B, Faure, F. Icarus, Volume 453, 15 July 2026, 117027 Voir en ligne : https://doi.org/10.1016/j.icarus.2026.117027 Visible Near-InfraRed (VNIR) spectroscopy is a powerful tool to assess the mineralogical composition of planetary surfaces remotely. Despite decades of investigation with the Observatoire pour

Regolith thickness across the Borealis Planitia region of Mercury

Joulaud M., Allemand P., Flahaut J., Füri E. Planetary and Space Science, Article n°106338, Volume 282, November 2026 Voir en ligne : https://doi.org/10.1016/j.pss.2026.106338 Mercury’s surface is covered by regolith produced by meteoritic bombardment, recording the planet’s impact and geological history. In this study, we assess the regolith thickness of the Borealis Planitia region (−72°E, 66°N),

Small Pluton Construction by the Stacking and Differentiation of Magma Sheets: Insights from the Beauvoir Granite (Massif Central, France)

Nicolas Esteves, Lydéric France, Michel Cuney, Pierre Bouilhol Journal of Petrology, Volume 67, Issue 7, July 2026, egag055 Voir en ligne : https://doi.org/10.1093/petrology/egag055 Constraining the links between the assembly of granitic intrusions and their magmatic differentiation processes remains a major challenge in igneous petrology. Although it has been suggested that most granitic intrusions are emplaced

Advancing Last Glacial Maximum paleoclimate reconstructions in Europe using pollen data: a multi-method (mega)biomization approach

Gabriel Fénisse, Manuel Chevalier, Odile Peyron, David Vincent Bekaert, and Pierre-Henri Blard Climate of the Past Voir en ligne : https://cp.copernicus.org/articles/22/1507/2026/ Pollen records are among the highest-resolution spatial and temporal proxies for reconstructing past vegetation dynamics, environmental changes and climate variability. Over the past decade, a large variety of methods based on different ecological or
